Velocity Effect in Swift Heavy Ion Irradiation: How the Low- and High-Energy Track Formation Thresholds Meet / R.A.Rymzhanov, N.Medvedev, A.E.Volkov // Journal of Materials Science [Electronic resource]. – 2023. – Vol. 58, No. 35. – P. 14072-14079. – URL: https://doi.org/10.1007/s10853-023-08898-2. – Bibliogr.: 31.

Variations of the threshold of swift heavy ion track formation with the ion energy and mass are studied here. We apply the hybrid multiscale approach combining TREKIS-3 code describing the electronic kinetics with the classical molecular dynamics tracing the evolution of the excited lattice. The results demonstrate that with a lowering of the energy loss curve (by choosing lighter ions for irradiation), the high-velocity threshold starts to shift down, whereas the low-velocity one remains constant until the thresholds meet. For certain ion parameters, a situation is possible in which both thresholds (low- and high-velocity) lie at the low-energy shoulder of the Bragg curve which results from the mismatch between the ion energy positions of the maximal track radius and the Bragg peak
